Travels in Geology: Discovering Denver's dinosaurs

A rich paleontological legacy makes Denver, Colo., one of the best places in the world to learn about dinosaurs, with numerous fossils and trackways at sites nearby.

Getting there and getting around Denver

Denver International Airport is the best arrival point for exploring Denver and the surrounding area. A car is necessary to see many of the attractions described here. If you fly in, you can rent a vehicle at the airport or take the new light rail into town and rent a car as needed. Although all of these sites are open year-round, snow sometimes obscures the tracks during winter and early spring, and trails can be muddy. May through October is an ideal time to visit the region.

Turtle finds lower Altiplano elevation estimate

Rare turtle fossils uncovered in Bolivia suggest that, about 13 million years ago, the southern portion of South America’s Altiplano — the arid, high-elevation plateau immediately west of the Andes — was far lower than previously thought.

Fossil leaves provide clues to ancient Australian habitat

Researchers have long thought that the scrublands of Australia developed over the last 25 million to 30 million years as part of a global trend toward colder and drier climates in which rainforests yielded ground to more open, fire-prone environments.

China's Red Deer Cave people may have survived until the last ice age

In the 1980s, a collection of bones from very small hominids was excavated from a cave in southwestern China, alongside a number of bones from a species of large red deer. Nicknamed the “Red Deer Cave people,” but not yet declared a distinct species, researchers previously dated radiocarbon in the sediments where the bones were found to about 14,000 years ago. In a new comparative study, the same team has now found that the hominids from which the bones came appear to have been similar to — although far smaller than — Homo habilis and Homo erectus, suggesting it could indeed be a new species.

Bat signals

Bats, the only true-flight mammals, first appeared during the Early Eocene after a period of acute global warming known as the Paleocene-Eocene Thermal Maximum. Despite decades of study, however, much remains unknown about bats. Recent discoveries are shedding new light on the natural history of these creatures, which today comprise one of the most diverse mammalian groups.

Inside an icthyosaur's brain

While the dinosaurs were busy ruling the continents in the Mesozoic, an order of marine reptiles known as the ichthyosaurs ruled the oceans. Ichthyosaurs are well known from numerous fossils, but they are often found flattened, limiting researchers’ ability to study the skulls and braincases as they existed in life.

A long layover on the Bering land bridge

About 11,500 years ago, two infants were laid to rest side by side in a shallow grave 80 kilometers southeast of what is now Fairbanks, Alaska. The area was once part of Beringia, a strip of ice-free land connected to Asia during the last ice age. Researchers found the remains in 2013, and have now sequenced the complete mitochondrial genomes of the two children. The results revealed that the infants had different mothers and that their genetic signatures are found today throughout North and South America.
